This invention relates to a valve-operating handle adapted to bedetachably mounted upon the outer end of a valve stem for openingandclosing the valve and refers more particularly to handles which aremolded `from bakeliteor other suitablematerial, by dies under pressuresomewhat inthe manner of die-casting. t i

Y It is frequently` desirable to provide the hubs .of 'these handleswith extension skirtsv which, together with the `main body ef` thehandled is adapted to enclose the portions of the valve stemextendinglbeyond thevalve case together with the means for securing thehandle tothe stem. v-

,fl It would, of course, belidesirable to mold the handle and; its skirtin one piece. 'butunderA the present methods of molding bakelite andanalogous ,materials it has been found to be impractical to mold theskirt-integral with the hand-le,V andthe main object of the presentinvention is to mold these parts 'separatelyin such `manner that theymay be easily and quicklyassembled one upon the other and upon thevalveistem without adding materially to the cost of manufacture.

Another object is toprovide the sections with telescoping parts splinedone upon the 4other to-turn in unison and for relative axialdisplacement. l t Y t A further object is to provide the skirt sectionwith a suitable shoulder* adapted to cooperaterwith a similarjstop onthe valve caseI for limiting the turning movement of the valve andhandle connected thereto. Other objects and usesrelating to specificparts of the devicewill be brought out in the following description.4 .j

Figures 5 and 6 are perspective views respectively of the main body andskirt of the handle. y l

Inorder that the invention may be clearly understood I have shown avalve case 1- containing 1a suitable valve i2- projecting outwardlythrough the usual gland 3+ of the valve case for receiving and1,supporting a. handle This handle comprises an outer end section or`main body ,-4- and an inner end section or skirt 4-5-, lthe outerendsection being provided with a. hub *6,- projecting inwardly beyond .theinner face of its outer portion, said hub ,being provided with a centrallengthwise opening -.-.7-. for receiving a portion `of the valve stem 2+andL suitable .fastening means such as a screw -8-. Theintermediateportion of the opening -7- adjacent the outer end of thehandle section A'-4- is reduced in, diameter to forma shoulder 9 againstwhich the outer end of the stem -2-7. u is adapted to abut, said stembeing `'provided in its outer end with a threaded socket for receivingthe threaded inner end of the screw ,-8- having its outer end enlargedfor engaging the shoulder -Qf and thereby firmly clamping the section-4- to the valve stem, (--y but permitting said section :to be easilyre.- moved by simplyrremoving'the screw -8 The portionV ofthe socket -7-and adjacent portion of the valve stem -2- eX- tending thereinto are ofangular cross section or otherwise formed to spline one part upon theother to cause the handle and valve stem to rotate in ,unison when handpower is appliedto the handle,

The inner end of thehub #-6- of the handle section --llf-` is reduced indiameter to form an annular shoulder `-10' against which the outer endof the skirt section -5 is adapted to abut when assembled thereon.

The outer end of the skirt section ,-54- is Y outer and inner sections-4- and 5'- to' cause them to turn in unison and also to allow them tobe displaced axially one from the other to be withdrawn from the valvestem.

The inner end of the skirt section 5;- is provided with a centralcylindrical socket lllof somewhat l`greater diameter than that of t-heopening -11- to form an annular shoulder v15- whieh is substantiallycto-incident with the inner end of thehub section --6-w when the outerendof the section Eiis engaged with the shoulder -10-.

This socket 14- is adapted to receive and enclose a coil spring-46'# anda pair owashers -17- and 18- which are interposed between the outer endot the spring *16- and ledge #l5- of the part -5- so that the outerwasher may be spring-pressed against the inner end of the hub and alsoagainst the shoulder -15- of the skirt -h to cooperate with the shoulderlO- for holding. the sections -4- and -5- against relative axialdisplacement when assembled for use;.

The portion of the valve stem -2- immediately adiacent the inner end ofthe hub is provided with an annular groove -l 9`v while the outer washer#17- refris teringwith said (rroove is provided with a radially elongrated opening -Q0.tlie outer endz of which is enlarged sufficiently topermit' it to he removed axially from the annular portion ot the valvestem when registered tlierewitlntlie inner end ot the radial openL intr-20- being of substantially the same diameter as the .qroove -l9- sothat when moved to its operative position. as shown in Figures 2 and 4.it will engage the walls of the groove and therehv hold the springv -16-under compression.

rThe central opening in the inner washer -1S- is of slifrhtlv @greaterdiameter'than that of the adiacent portion of the valve .stem so thatwhen the outer washer 1T- isremoved from the valve stem the inner washerand also the spring, -16- may also be removed endwise by outwarddisplacement.

The inner end section -5 of the handle is provided with an outwardlyprojecting' peripheralprojection 2lforming a stop shoulder which isadapted to cooperate wit-h another stop shoulder -22- on the outer endof the `gland -3- for limiting the turning movement of the handle andvalve actuated thereby in opposite directions, and thereby to indicatethe open and closed positions of the valve, as shown more clearly inFigure 4.

That is, when the handle is turned in a clockwise direction the stopshoulder or pointer -21- will approach closely to the stop -22- inregistration with the indicia Shut On the other hand, whenv the handleis turned in a counterclockwise direction the stop shoulder or pointer-21- may be brought into engagement with the stop shoulder -QQL- or inregistration with the indicia Open to indicate that the valve is open.

lVhile I have shown and described the manner of assembling' the handlesections one upon the other and upon the valve stem, it will heremembered that the main feature of the invention consists in moldingthe outer and inner handle sections separately so that they may betelescopically assembled one within the other and splined one upon theother to cause-them to rotate in unison, and that when securedv upon thevalve stem by means of the screw -8-` both sections will turn togetherwith the valve stem.

It is evident, however, that certain changes may be made in theconstructiony ot' the two sections ot the handle without departing fromthe spirit or object of the invention.

That I claim is 1. A handle for valve stems comprising an outer endsection having its inner end re` abutting.r against said shoulder` thetelescoping portions of said sections being.)r splined one upon theother to turn together, the inner end section having a stop shoulderadapt'- ed to co-operate with a companion stop on the valve case forlimitingY the turning movement of the handle about its axis..

3. A handle for valve stems comprising outer and inner co-axial sectionshavingitelescoping parts splined one uponthe other, the inner sectionhaving. a socket in its inner end of greater diameter than that of theadjacent end of the outer section to receive a portion of thevalve-operating. mechanism.

4. A handle for valve stems comprising outer and inner co-aXial sectionshavingr telescoping` parts splined one upon the other, the inner sectionhavimgy a socket in. its inner end of `greater diameter than that of theadj acent end of the outer section to receive a porizo tion of theValve-operating mechanism, said outer section having a centrallengthwise opening for rece1v1ng a portion of a valve stem.

5. The combination with a valve stem, of

a handle composed of outer and inner c0- aXial sections havingtelescoping parts splined one upon the other, the inner section havingav socket in its inner end of greater diameter than the adjacent end ofthe outer section to form an annular shoulder, means for locking theouter section to the valve stem against relative endvvise or turningmovement, and means Within the socket engaging said shoulder for holdingthe inner section against inward endwise 'displacement from the outersection.

In Witness whereof I have hereunto set my hand this 29th day of January1931.
